1 Claim.

This invention relates to screw valves, and more specifically, to screwvalves which are particularlyY adapted for use on large wine tanks orthe like.

It -is an important object of the invention to provide a screw valve ofthe character described which is capable of being disassembled despiteits being mounted in an opening in a tank, and serving as a closure ofsaid opening. By way of explanation, it might be pointed out that suchdisassembling is desirable in order that there may be a minimumprojection of the valve from the tank. The contents of tanks of the typedescribed are insurable, and premium rates commonly take into accountthe obstruction presented by a valve to articles which may be moved pastthe tank, or which may accidentally fall against the tank, breaking thevalve open and causing a loss of liquid from the tank.

It is a further important object of the invention to provide a valve ofthis type which, though capable of serving its purpose even whendisassembled, will, nevertheless, be fully eiiicient in sealing liquidswithin the tank, without danger of leaks and the like.

Still another important object is to provide a valve which is capable ofeasy and simple operation, is at all times positive in fullling itsfunction, and which is simply and strongly constructed.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts, hereinafter more fully describedand pointed out in the claim, it being understood that changes may Ibemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawing Figure 1 is a longitudinal and substantiallyvertical sectional view through a screw valve constructed in accordancewith the invention.

Figure 2 is a view taken on line 22 of Figure 1.

Referring to the drawing in detail, the invention embodies asubstantially cylindrical hollow body portion 5, externally threaded formounting in the threaded opening of the stave 6 of a 'wooden tank. Inthe embodiment of the invention presented by the drawing, the bodyportion is shown as tapering in form, and this adapts it particularlyfor use in wooden tanks. However, it may if desired be fully cylindricalin form, for use in tanks constructed of other materials, in which eventit is best provided with a lock nut on its interiorly projecting end.

At its inner end, the body portion 5 is open, providing a seat for avalve l, the rear surface of which is formed with a cylindricalinternally threaded socket 8. I

Within the body portion 5 an annular hollow sleeve 9 has a threaded borecoaxially aligned with the bore of the socket S. A plurality of stripsI0 support the sleeve 9 in desired position.

At its rear end, the body portion 5 is cylindrical, and is externallythreaded as shown at I I, whereby it may be attached to the spout I2 bymeans of the internally threaded screw collar I3. As clearly shown inFigure 2, the screw collar I3 is formed in halves that are connectableby bolt and nut means I4,v in order that it may be tightened inposition, preventing leaks. The' adjacent end of the spout l2 has anannular groove I5 cooperating with an annular rib I6 on the screw collari3, and between the abutting edges of the body portion 5 and spout I2there is a gasket Il, further sealing the connection against leaks.

To the outlet I8 of the spout I2 is threadedly attached a cap I9, whenthe bung valve is not being used. A washer 20 in the cap |'9 seals theconnection between the cap and the outlet I8 at such times, so as toprevent leaks,

Integral with the spout 2 is a cylinder or sleeve 2| that has a borecoaxially aligned with the bore of the sleeve 9 and of the socket 8, therear orouter end of the cylinder 2| having eX- ternal threadscooperating with internal threads on a packing gland nut 22, that holdsin place a nipple 23, packing 24, and a washer 25.

Extending through the cylinder 2| and rotatable by the handle 26 is thevalve stem 21, having an enlarged threaded portion 28 that coopcrateswith internal threads in the cylinder 2|, so that the valve stem may bemoved forwardly and rearwardly so as to open and close the valve 1.At'its forward end, the valve stem 21 is provided with a bore or socket28 which has a squared inner surface for receiving the squared rear end29 of a valve rod 30.

This arrangement, as may be seen by referring to Figure 1, permitsdetachment of the spout |2 from the body portion 5 without anydisassembly of the valve-actuating means other than removal of thesquared end 29 of the valve rod 30 from the socket 28 of the valve stem21. In addition, the squared engagement causes the Valve rod 30 torotate with the valve stem 2l during opening and closing of the valve Asreadily noted 3 by comparison of the length of the threads Il with thelengths of the socket 28 and stud 29, the connection of the valve rodand stem for joint rotation is maintained in any position of the Spannernut I3 relative to the body portion 5.

Maintaining the valve rod 30 in desired position is the sleeve 9,through which the valve rod is threaded.

At its forward end, the valve rod 30 is formed with a headv 3l that isheld tightly against the inner end of the socket 8 by a lock nut 32threaded into the socket. Thus, rotation of the valve rod in the mannerhereinbefore described will cause the valve I to be moved forwardly fromits seat, opening the valve so that liquids held by the tank may freelypass through the device and be discharged from the outlet I8.

In addition, it is pointed out that in detaching the spout I2 from thebody portion 5, there would be no leakage from the device, since thevalve rod 30 will in this event be left in the body portion 5, and byreason of its threaded engagement with the sleeve 9, will eiectivelyhold the valve I in fully closed position despite the partialdisassembly of the device indicated herein.

In connection with detachment of the spout I2 from the body portion 5,the outer circumference of the threaded outlet I8 may be constructed soas to be equal tothe outer circumference of the threaded rear end I I ofthe body portion 5. This will permit the use of the cap I9 as anattachment to the body portion 5 when the spout I2 is detached.

In the latter event, the projection of the device from the tank, withthe spout I2 having been removed, would be very slight, providing adesirable protective feature in the event of heavy articles accidentallystriking the device in being moved past the tank, or in the event of asimilar accidental occurrence.

Whatis claimed is:

A valve assembly including a hollow body portion adapted for stationarymounting in a tank wall opening, an internally threaded sleeve mountedwithin the body portion and spaced from the wall thereof to provide aclearance for liquid passing through the body portion and around thesleeve, a solid valve rod threaded in the sleeve and having one endformed noncircularly, a valve disc on the other end of the rod andadapted to seat against one end of the body portion to close the same, aspout, a screw collar swivelled on the spout and threaded on the otherend of the body portion, said spout having internal threads identical tothe threads of the sleeve, and a valve stem threadedly'engaged in thespout and having a noncircular socket at one end slidably andnon-rotatably receiving the noncircular end of the valve rod when thescrew collar is threaded upon the body portion to connect the bodyportion and spout, the socket and noncircular valve rod end respectivelybeing of lengths to cause maintenance of the connection for jointrotation therebetween in any position of threaded engagement of thescrew collar with the spout, the like threads on the coupled valve rodand stern being disposed at opposite sides of the s'udable andnon-rotatable connection therebetween and constituting means holding thevalve rod and stem against relative longitudinal movement in eitherdirection during threaded advancement and retraction of said valve rodand stem.
